I have a 2004 ES330 once a hestitation problem. It is good from a full end but gone I go as regards turns on onto highway ramps, subsequently I depress the accellarator (sp?) it hesitates for 2 seconds past reving up. I ve taken it to a mechanic and he says it is normal. I have an 2003 Avalon past the same engine and it jumps off the begin and has no hesitation. Mechanic s Assistant: Will the headlights twist on? Is the battery thoroughly charged? With or without headlights on. Relatively supplementary battery. Mechanic s Assistant: What is the model of your 04 Lexus? ES330 Mechanic s Assistant: Are you fixing your vehicle yourself? What have you tried consequently far? I ve cleaned the MAF sensor. Checked for links in the intake. past I put my Turbo OBDII app on, all seems good except that the TPS stays constant on the order of 30%. This is a drive-by-wire model consequently it has not throttle cable or normal TPS. I undertake the TPS is integrated subsequently the throttle controller/motor. Mechanic s Assistant: anything else you want the mechanic to know past I connect you? No, I guess that is it.
I started the car happening this morning, it starts in the works and runs at 1750 and within a minute or therefore climbs exceeding 2500.. It is presidency serene though, just showing off future than it should be. I afterward checked the throttle screw plate/return screw, purposefully turned it out and nothing changed. put it urge on to exactly where it was. No vacuum leak sounds and all contacts verified. I atmosphere good virtually them as I've been in there a bunch of times..
I don't have any check engine lights unless I unplug the MAF sensor. in the manner of the MAF is plugged in then the car will stall unless I put my foot on the accelerator. There is then an intermittent popping solid coming at idle.
